Much of the methods are inherited from Bar. A Column Chart is a useful visualization technique to display quantitative information for different
categories that can show some progression (or regression) in the data set.
As with all other series, the Column Series must be appended in the <em>series</em> Chart array configuration. See the Chart
documentation for more information. A typical configuration object for the column series could be:</p>

<p>In this configuration we set <code>column</code> as the series type, bind the values of the bars to the bottom axis, set <code>highlight</code> to true so that bars are smoothly highlighted
when hovered and bind the <code>xField</code> or category field to the data store <code>name</code> property and the <code>yField</code> as the data1 property of a store element.</p>

<p>This option is useful during Component construction to add DOM event listeners to elements of <a href="Ext.Component.html" rel="Ext.Component" class="docClass">Components</a> which
will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
<pre><code>new Ext.panel.Panel({
    title: 'The title',
    listeners: {
        click: this.handlePanelClick,
        element: 'body'
    }
});

<p></div></li>
</ul><br></p>

<p>
<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A delayed, one-time listener.
<pre><code>myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple events. For example:
<pre><code>myGridPanel.on({
    cellClick: this.onCellClick,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    scope: this // Important. Ensure "this" is correct during handler execution
